Product Info Large size conveyor chain
Large size conveyor chain can be freely combined to transport materials in any direction, including horizontal, vertical, and inclined orientations. They can withstand temperatures up to about 200°C without the need for special materials, and heat-resistant steel is used for higher temperatures. They also come in specifications that are corrosion-resistant and chemical-resistant to water and chemicals, making them suitable for a wide range of applications.
Almost any material can be transported, from powders such as pulverized coal and cement to granular materials such as wheat and soybeans, lumps such as ore and rocks, and even products weighing several tonnes each, and there are almost no restrictions on the materials that can be transported.

Operation
Structure
Screw Lock Link
A connecting link that enables safe and fast work.
Note: Due to the nut system, the pin length is long. Please check that it does not interfere with the device.
*The overall length tolerance for Large size conveyor chain is ±0.25%.
■ slip fit
When a shaft and a hole are fitted together, there is always a gap.
A fit in which the tolerance area of the hole is entirely above the tolerance area of the shaft (pin or bush).
■ press fit
A fit that always creates an interference when the shaft and hole are combined.
A fit in which the tolerance range of the hole is completely below the tolerance range of the shaft (pin or bush).

| 1. Pin (CP) | 2. Bush (B) | |
|---|---|---|
| The most important role of pins is to connect outer link and Inner link. Like the plates, they receive chain tension in the direction of travel and reaction force from the transported goods in the perpendicular direction. Furthermore, when the chain articulate, the outer circumference of the pin slides against the inner circumference of the bushing, causing wear. Pins are an important strength component, but they also need to be wear-resistant. | The bushing is a strength component that receives the tension of the chain when it meshes with the sprocket, but its main function is as a bearing component. The outer circumference of the bushing wears out as it slides against the inner circumference of the roller when the roller rotates, and the inner circumference of the bushing wears out as it slides against the outer circumference of the pin when the chain articulate. Wear on the inner circumference of the bushing directly appears as pitch elongation. | |

| It has a slip fit with the bushing.. When it meshes with the sprocket, it acts as a roller, mitigating impact and wear on the tooth surface. It also rolls when traveling, reducing rolling resistance. | The plates are primarily subjected to tensile loads in the direction of chain travel, and to reaction forces at right angles to support the transported load. When the chain articulate, the outer and inner plates slide against each other, and when it engages with the sprocket, they slide against the side of the teeth. Generally, the outer plates have round or notched holes. | |

After press-fitting the pin into the outer plate, insert a T-pin and bend it to prevent the pin from falling out. Bend it by more than 30 degrees or until the end of the T-pin fits within the width of the plate. | This is the part that secures the attachment. For information on attachment types, see "Attachment Types" below. |
■The three basic dimensions of chains
Pitch, roller diameter, and Inner link width are called the three basic dimensions of a roller chain. When these dimensions are the same, the roller chain and sprocket are dimensionally compatible.
Attachments are parts for attaching transport fixtures to chains. They can be installed at desired link intervals.
Standard Attachment
This is an economical and versatile attachment.
A attachment
It has a blade on one side.
They are called A1, A2, and A3 depending on the number of bolt holes.

Safety Precautions
Never weld additional parts to an assembled chain, as this can cause the chain to bend or twist due to plate distortion and can also cause the parts to lose hardness or become brittle due to heat.
